The corrido is a popular narrative song and poetry form, a ballad. The songs are often about oppression, history, daily life for peasants, and other socially relevant topics. It is still a popular form today in Mexico and was widely popular during the Nicaraguan Revolutions of the 20th century. The corrido derives largely from the romance, and in its most known form consists of a salutation from the singer and prologue to the story, the story itself, and a moral and farewell from the singer.
